RETURN TYPEOwned native handle

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Native object: release it with using or delete(). Factories can return null; check before calling methods. Inherits Algorithm.

Abstract base class for stateful silhouette trackers

Constructors and members

clone

Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.

clone(): this;

Returns

The this result.

compute

Estimate the pose of the tracker's configured 3D model from image edges, updating rotation and translation arrays.

compute(img: Mat, num: number, len: number, K: Mat, rvec: Mat, tvec: Mat, termcrit: TermCriteria): number;

2 available overloads

compute(img: Mat, num: number, len: number, K: Mat, rvec: Mat, tvec: Mat): number;

compute(img: Mat, num: number, len: number, K: Mat, rvec: Mat, tvec: Mat, termcrit: TermCriteria): number;

img

img argument (Mat).

num

num argument (number).

len

len argument (number).

K

k argument (Mat).

rvec

Input/output value, modified by the native operation. rvec argument (Mat).

tvec

Input/output value, modified by the native operation. tvec argument (Mat).

termcrit

termcrit argument (TermCriteria).

Returns

The number result.

Upstream declaration ↗

clearState

Discard the tracker's accumulated internal state before tracking a new sequence.

clearState(): void;
